An Eye-Opening Arbiter PUF With Auto-Error Detection and PVT-Robust Masking Achieving a BER of 2e-8 150 150

Abstract:

A hybrid ring oscillator (RO)/ arbiter physical unclonable function (PUF) is implemented in a 28-nm CMOS, where two competing ROs accumulate a sufficiently large phase difference exceeding a predefined deadzone (DZ). The resulting eye-opening arbiter (EOA) architecture enables a prediction of PUF bit stability over temperature change (from −40 °C to $125~^{\…

High-Entropy Analog-Based Strong Physical Unclonable Function With Area-to-Entropy-ratio of 166 F2/bit

High-Entropy Analog-Based Strong Physical Unclonable Function With Area-to-Entropy-ratio of 166 F2/bit 150 150

Abstract:

In this letter, we present a high-entropy strong physically unclonable function (PUF) utilizing weak-inversion current mirrors implemented in a standard 65-nm CMOS technology. Each response bit of the proposed PUF relies on the threshold voltage differences of minimum-sized transistors arranged in a $32\times 32$ matrix. The analog operating principle enables encoding …
